Patent CA-2038545-A1 (CA)
Inventor: LUTZ DALE R
IPC: G01R15/24
Filed: 1991-03-18
Abstract: In known Faraday effect current sensors, light is fed into a polarizer, through a coil of field-sensitive optical fiber, and into a polarization measuring device.      Such a current sensor can provide greater accuracy of current measurement by using a polarizing optical fiber as its polarizer and splicing the polarizing fiber to the input end of the optical fiber coil. The exit end of the optical fiber coil can be spliced to a second polarizing optical fiber, the other end of which is optically connected to a photodetector. In another embodiment, a mirror at the exit end of the optical fiber coil reflects light back through the coil to second and third polarizing fibers which in turn are optically connected to a pair of photodetectors, thus doubling the Faraday rotation while canceling out reciprocal optical effects.

Abstract: A phantom keyboard is formed on a touch sensitive display as an input tool for a computer. The keyboard is superimposed on, though does not occlude from view, an image of an output of an application being run on the computer. In a another aspect of the invention, the simulated keyboard is displayed in a different fashion, in a window occupying, e.g., the bottom of the display rastor, while the application's output appears in a window occupying, e.g., the top of the display rastor. Since this arrangement provides only a fraction of the full rastor for displaying the output from the application program, a special scroll feature is provided. This feature permits the user to scroll through the full screen page of text, but without the text of any other screen pages appearing on the display. In yet another aspect of the invention, the key "auto-repeat delay" and "auto repeat rate" of the simulated keyboard are user adjustable, again preferably by an adjust appearing on the touch-sensitive display.

Inventor: HANNA PETER D
IPC: B65H9/10
Filed: 1991-09-27
Abstract: An apparatus for moving a document towards the bottom of a document track as the document is moved in first and second directions within the track. The apparatus includes a feed unit positioned on one side of the document track and a cooperating unit positioned on the opposed side of the track.  The cooperating unit has a rod which is pivotally supported in a support.  A high friction roller is secured to the top end of the rod and a low friction roller is rotatably supported on the lower end of the rod.  The feed unit has an idler roller positioned opposite to the high friction roller and also has a drive roller positioned opposite to the low friction roller in the cooperating unit.  As the document is moved in a first direction in the document track, the high friction roller causes the rod to pivot slightly, thereby causing the low friction roller on the bottom of the rod to cant slightly, producing a downward component of force on the document as it is moved in the first direction.  When the document is moved in the opposite direction, the low friction roller is canted slightly in the opposite direction to produce a downward component of force on the document as it is moved in the second direction.

IPC: G01L9/00
Filed: 1991-10-31
Abstract: Microminiature pressure transducers are formed on semiconductor substrates such as silicon and include a membrane which spans a cavity over the substrate, with the membrane being mounted to and sealed to the substrate at the peripheral edges of the membrane.  The bottom of the cavity forms an overpressure stop to prevent over deflections of the membrane toward the substrate.  An overpressure stop formed as a bridge of a material such as nickel extends above the membrane and is spaced therefrom to allow the membrane to deflect freely under normal pressure situations but prevent over deflections.  The thickness of the polysilicon membrane and the spacing between the membrane and the overpressure stops is preferably in the range of 10 micrometers or less, and typically in the range of one micrometer.  The overpressure stop bridge is formed utilizing deep X-ray lithography to form a well-defined bridge structure.  The gap between the membrane and the bottom surface of the bridge is established with a sacrificial layer, such as a polyimide film, which dissolves in a solvent.  The transducer is formed utilizing processing techniques which do not affect the performance of the membrane as a pressure sensor and which allow the substrate to have further micromechanical or microelectronic devices formed thereon.

Title: Control system for regulating the axial loading of a rotor of a fluid machine

Filed: 1991-03-07
Abstract: CONTROL SYSTEM FOR REGULATING THE AXIAL LOADING OF A ROTOR OF A FLUID MACHINE                    ABSTRACT OF THE DISCLOSURE    The axial forces imposed on a rotor of a fluid machine such as a compressor is controlled by modulating the pressure supplied to a piston and cylinder device acting between the rotor shaft and housing.  A parameter indicative of axial force on the rotor during operation is monitored and changes in the magnitude and direction of the axial forces countered by varying the pressure in the cylinder.  The net axial forces imposed on the shaft may thus be controlled in a predetermined range.     This invention may suitably be used to control the axial thrust free on the rotor shaft of, for example, a gas compressor.

Abstract: The invention is an improvement in a machine such as a surface mining "shovel" having an arm,  a bucket-like digging dipper and a brace.  The latter is used to maintain a selected "rake angle" between the arm and the dipper.       The brace has first and second end lugs and extends between the arm and the dipper.  The improvement comprises a tube-like collar interposed between and connecting the lugs.  At least the first end lug is positionally adjustable with respect to the collar so that the "rake angle" between the arm and the dipper may be readily selected.   In a highly preferred embodiment, each end lug  is  threaded to an opposite end of the collar and better "vernier" adjustment of the rake angle results.  Each threaded lug has at least one threaded groove engagable by a screw passing through the collar to prevent relative rotation of the lug and the collar.
